Return Value

true if the sound is playing back successfully; otherwise, false.

Play will return false if there too many sounds already are playing.

To loop a sound or apply 3D effects, call CreateInstance instead of Play, and SoundEffectInstance.Play.

Sounds play in a "fire and forget" fashion with Play; therefore, the lifetime of these sounds is managed by the framework. These sounds will play once, and then stop. They cannot be looped or 3D positioned.

Silverlight applications must ensure that FrameworkDispatcher.Update is called regularly in order for "fire and forget" sounds to work correctly. Play throws an InvalidOperationException if FrameworkDispatcher.Update has not been called at least once before making this call.
